如何在关机时使得dos程序正常关掉?我是vb初学者,参考资料编了个程序实现了dos程序界面windows化,既使用了winexec来调用一个dos程序(有窗体),但问题出现在关机,重启和注销时,一到这个时候就会弹出windows无法自动关闭此程序的对话框,我又重编试图拦截关机消息,但总是不成功,请问这种程序怎样实现?

你的 DOS 程序有窗口么?
有的话,在关机,重启和注销前先用 FINDWINDOW 找到它的窗口,然后用 SENDMESSAGE 发送 WM_CLOSE 消息给他关闭.
在发送消息后加一点延时以等待其关闭Top

我说的那个程序和command.com不一样,只要你去关它,它就弹出“windows 无法自动关闭此程序,建议使用‘退出‘ 命令退出“,所以关机时也一样会谈出这个对话框。

所以我又添加了一个timer函数,在timer中用另外一个程序关闭这个窗口,调试成功,有新的问题再次联系。测试方法如下
先打开两个dos窗口
运行project1.exe
再打开两个dos窗口
注销,dos窗口先打开的直接被关闭,后打开的出现立即结束窗口后被关闭,速度取决于timer的设定测试环境: xp, vb6代码如下'窗体
